in this manual and always obey the instructions.
•
Only operate the analyzer in closed and dry rooms, protect
the analyzer against rain and moisture.
•
Only operate the analyzer with the supplied battery
charger.
•
Never us the probe tube and other metal parts / accesso-
ries as electric conductors.
•

Analyzer details
•
The analyzer is not suitable for long term (
continuous)
measurements (this is a spot analyzer).
•
Before using the analyzer verify the condition of the vari-
ous parts of the analyzer, such as the probe, the ambient
air conditions, the condensate separator, star filter and the
connectors for damage and/or blockages.
•
When starting the analyzer up it will take between 1
–
3
minutes to set to zero depending on the condition of the
sensors and ambient conditions.
(Zeroing).
•
The minimum zeroing time of the analyzer to achieve cor-
rect measurement values can be expected by 1.5 minutes!
•
Exposure to acids; aggressive gases such as Sulphur; va-
pours such as thinners, gasoline, alcohol and paint, etc.
can damage, reduce the life of, or destroy the sensors.
•
The life of the sensors depends on how they are used,
maintained and treated. Typical average life expectations
are: O
2
- 2 years; CO - 2 - 3 years and NO - 3 years.
•
The battery life is at least 500 charge-discharge cycles.
With increasing number of charging cycles the battery ca-
pacity (indicated in operating hours) is reduced.
